Hello, Can somebody help me on a colour question? I have a levelplot made with the following syntax: library(lattice) inp <- read.csv("hoenne1", header = TRUE) levelplot(z~x*y, data = inp, region = TRUE, pretty = TRUE, col.regions = terrain.colours) The file "hoenne1" contains the data. I'll give a short example: x,y,z 0,0,1 0,1,1 0,2,1 1,0,2 1,2,2 0,2,2 1,2,3 2,2,2

Hi all, I wonder why there is so little software for carpet plots (german: Rasterdiagramm) (Three dimensional plot (x, y, z), the 3rd dimension (z) symbolized by colourgradients). Besides from one or the other non free software I only found an OpenOffice macro, a combination of Gnuplot and Excel (an Excel macro calling gnuplot) (http://www.johannes-hopf.de/2009/12/carpet-plot-version-1-3/9 and

Hello, I got R 1.6.0 for windows and I need Rcmd, which was not included. Where can I get it? (I have to start R and give the name of the file with the R-commands on the command line, so that R is invoked together with its command-file "todo.R". Do I really need Rcmd for that? To write "Rterm todo.R" did not work.) Richard -- Richard M?ller - Am Spring 9 - D-58802

Hello, the admonition of Prof. Ripley to search the documentation to solve my problem helped, today I read a lot more on Tcl/Tk than before ;-) But now I'm stuck again. With the help of my script some functions are plotted on the display, then I ask if the user wants to save it as pdf. In windows I use winDialog and it works. But I can't succeed in Linux. In short:

Hi all, I'm using winDialog and winDialogString in scripts running on a XP-machine. Since we're using some Linux-machines (Suse 10.0 and 10.1 on x86) I'm interested in equivalents of the above functions usable under Linux-OS. Are there any?

DeaR R-fellows, I got a lot of help from you concerning the generation of heat maps, so I was able to write and work with a script for this purpose at last. Some visitors of our Ecological Station asked about the generation of the graphs and so I decided to write down a small description. Is it adviseable to publish the link to the article in an R-wiki (which?) so I can give back a little to the

Dear R-community, In graphical representations of findings concerning bodies of standing water (lakes e.g.) in x-y-plots you often make use of a somewhat different definition of coordinates in a cartesian system: the origin is top-left, the x-axis (depth of the water body) from top to bottom and the f(x)-axis from left to right, so you can project the graphical representation of data in your

Hello, I have a long list of x-, y- and z-data and try to generate a heatmap. Obviously there are several data with identical x- and y-values. I get the following error message: Error in interp.old(x, y, z, xo = xo, yo = yo, ncp = 0, extrap = extrap, : duplicate data points: need to set 'duplicate = ..' Unfortunately there seems no help screen on "duplicate". I'd prefer

Dear list, I encounter a strange problem: I hav R (1.6.1) installed on a notebook with winXP-Prof and a similar installation (same path names etc.) on a desktop computer with W98. I use rcmd BATCH filename to display graphs from the data stored in filename. With R on my notebook everything works fine. I have the same data, the same filenames, the same paths on th w98-computer. Here I see just a

Hello, R users, I am a very beginner of R and tried read.csv to import an excel file after saving an excel file as csv. But it added alternating rows of fictitious NA values after row number 16. When I applied read.delim, there were trailing several commas at the end of each row after row number 16 instead of NA values. Appreciate your help. Kyong [[alternative HTML version deleted]]

Hi, I hope this is my last stupid question for this project. I run (WinXP) Rcmd* BATCH ToDo.R and want the produced graph to be seen on the display. But after a part of a second the graphics window is closed again. I suppose, because Rcmd does not work interactive, there will be no command like "wait for key pressed" or similar. Is there a possibility to let the window open as long

Good evening, I can't manage to plot continous lines (x-y representation of measured data): The spreadsheet where the data come from has continuous x-data (0,1,2,3,4, ...), but not every x-datum has a corresponding y-datum. At these "gaps" the graph is not displayed. I want to display the measured data with points, joined by a line ("type=b"), even if there are gaps. Is

Hello all, to interrupt a BATCH program I inserted, as adviced in this list, a windows dialogue box (winDialog("ok")). The graphic display opens on the right part of the screen, which is OK. The Windows dialoge opens in the center of the screen and hides a part of the graphics window. Is it possible to determine the coordinates where the Windows dialogue box opens? I'd like to

hello respected ppl... am a engg. student...i was trying to use R in statistical calculations now the problem is..i imported a huge tsv file onto R...it has a column which gives cost...and it has "$" with each numerical value in this column...it is something like this..$.05,$.1,$.075...and so on.. R is reading it as "character vector"... i tried using all the arguments but

Hello, I have the TCl/Tk command "tkmessageBox(titel="",message="x",icon="question",type="okcancel")" in my R script. Now I want to perform some operation in relation to the user's choice, something like "if (okpressed) xxx else yyy" What values does this command give and how are they used? Thank you, Richard -- Richard M?ller -

Hi there, as I'm not sure to understand the coloring levelplot uses, I'm looking for another easy way to create a heatmap like this: library(lattice) mat <- matrix(seq(1,5, length.out = 12), nrow = 3) mat[1,2] <- 3.5 my.at <- seq(0.5,5.5, length.out = 6) my.col.regions <- rainbow(5) graph <- levelplot(t(mat[nrow(mat):1, ] ), at = my.at, col.regions = my.col.regions)

Hi there, I'd like to create a heatmap from my matrix with a) a defined color range (lets say from yellow to red) b) using striking colors above and below a certain threshold (above = "green", below = "blue") Example matrix (there should be a few outliers generated...) + simple levelplot without outliers marked: library(lattice) my.mat <- matrix(rnorm(800), nrow =

Hi, How do I anchor z=0 to the white color in a levelplot so that the color changes from cyan to magenta precisely as z changes from negative to positive? Also is it easy to change color scheme, say to blue/red as it's more dramatic? Is there a better function for showing heatmap with a color bar? Thanks in advance for any help, I've played with image, heatmap and levelplot a little and

Hello! I have data containing a large number of probabilities (about 60) of nonzero coefficients to predict 10 different independent variables (in 10 different BMA models). i've arranged these probabilities in a matrix like so: (IV1) (IV2) (IV3) ... p(b0) p(b0) p(b0) p(b1) p(b1) p(b1) p(b2) p(b2) p(b2) ... where p(b1) for independent variable 1 is p(b1 !=
